The most likely negative consequences of plastic surgery of the penis in order to thicken it are the formation of soft tissue edema, hematomas, the addition of a secondary infection (with a focus of inflammation), proliferation of connective tissue with scarring.
Complications of autoimplantation of the skin-fat flap are thickening of the tissues of the penis, its curvature and shortening, as well as graft fibrosis.
The use of allografts to thicken the penis is complicated by the formation of erosion, as well as the development of fibrosis and skin resorption, which can shorten the length of the penis and impair its function.
According to clinical data, severe edema of the penis and the development of ischemic ulcers are complications after implantation of the collagen matrix.
Lipofilling does not give a long-term stable result (maximum two years), as there is a gradual resorption of adipocytes. And mechanical trauma to the penis during the procedure can cause fat necrosis.
In addition to the complications of liposuction , the introduction of adipose tissue into the penis can lead to complications such as the formation of cysts, lipogranulomas and seromas, as well as tissue microcalcifications. As a result, the asymmetry of the penis and the tuberosity of its surface are observed.
Immediately after the injection of the gel with hyaluronic acid, the skin color temporarily changes, edema forms and local numbness occurs. With the superficial introduction of the gel filler (or exceeding its volume), the formation of granulomas is possible. After some time, this procedure can not only reduce the sensitivity of the penis and lead to erectile dysfunction, but also provoke fibrosis.
Therefore, to date, cosmetic fillers are not approved by the FDA for use on the penis, and experts from the International Society for Sexual Medicine also do not recommend their use in phalloplasty.
